- FIG. 1 shows a front right view of a portable water purification system 100 in accordance with embodiments.
- the portable water purification system 100 comprises a tank or other water storage receptacle 102 , a pump 104 , and a filter 106 .
- the water storage receptacle 102 may be made of any suitable material, but in many embodiments, the water storage receptacle 102 comprises food grade plastic so as to provide a sanitary storage container for drinkable water, such as the drinkable water produced in accordance with various embodiments by water purification system 100 .
- a filter 106 in portable water purification system 100 can be any porous material through which water can be passed in order to remove at least some particulate matter from the water.
- a wide variety of filter 106 materials and methods are known in the art, including reverse osmosis filters 106 .
- a reverse osmosis filter 106 receives an input of water containing a certain starting concentration of contaminants or impurities and produces two outputs: purified water with a contaminant concentration much lower than the starting concentration and brine water with a contaminant concentration higher than the starting concentration.
- a reverse osmosis filter achieves this result by the use of a pressure differential across a selective membrane.
- the selective membrane has pores sized to be smaller than a contaminant particle size but large enough to allow the passage of water molecules.
- contaminant-bearing water is placed under sufficient pressure on a first side of the selective membrane, water molecules pass through the membrane to the second side, while the contaminant particles too large to pass through the membrane pores are retained on the first side.
- the water accumulated on the second side provides the purified water output, while the water on the first side—with the retained contaminants—provides the brine output having a higher concentration of contaminants (i.e., the concentration increases on the first side of the selective filter because the amount of water there decreases—due to water siphoning off through the selective filter—but the total amount of contaminants remains the same).
- salt is the targeted contaminant
- a reverse osmosis filter 106 can receive an input of seawater or other saltwater and produce a freshwater or at least drinkable (i.e., potable) output and an output of brine having a salt concentration slightly higher than the input saltwater.
- a source water intake 108 can be connected to a source of water to be purified (e.g. salt water or water containing an undesirable level of contaminants), such as by a hose, pipe, tube, spigot, spout, or other appropriate conduit.

Abstract
Description
- Over two-thirds of the Earth is covered with salt water, and there is a relatively unlimited supply of solar energy. On the other hand, it is becoming clear that access to fresh water will be one of the biggest challenges for humanity in the 21st century. Unfortunately, in many areas of the world there is limited access to fresh water sources.
- In some instances, the lack of access can be attributed to a lack of electricity and power to filter water effectively. Poor areas, for example, typically cannot afford the costs required for installing infrastructure for electricity. In other instances, the lack of access can be attributed to a disaster. Often disasters such as hurricanes or earthquakes can cause a sudden great need for fresh water to meet basic hydration needs of victims, while simultaneously destroying any freshwater reserves, contaminating freshwater sources, and/or drastically damaging infrastructure and the ability to transport large supplies of relief fresh water.
- Accordingly, purifying water in these environments is an ongoing challenge, since increasingly worse and more extreme conditions call for purification systems to be increasingly eco-friendly, durable, inexpensive, and readily portable.

- Disclosure herein is directed to a portable water purification system. In embodiments disclosed herein, various components of a water purification system during travel can be housed inside a receptacle that can also be used during operation to contain the purified water produced by the system. Such functionality can be advantageous in a variety of ways. For example, such an arrangement can be a more efficient use of space which allows an increased ease of portability due to a reduction in cargo space needed to transport all of the requisite parts needed for purification. Additionally, a compact configuration can also help a purification system to have a small footprint, making it easier to manage, operate, store, and/or maneuver. Furthermore, use of a common container for all components can help keep all of the necessary parts together, diminishing the risk that the system could become inoperable due to a piece becoming lost. Benefits can also include ease of setting the system up and/or packing it up, particularly when components have designated storage and/or operational positions.
- Referring now to the drawings, in which like reference numerals represent like parts throughout the several views,
FIG. 1 shows a front right view of a portablewater purification system 100 in accordance with embodiments. In embodiments, the portablewater purification system 100 comprises a tank or otherwater storage receptacle 102, apump 104, and afilter 106. Thewater storage receptacle 102 may be made of any suitable material, but in many embodiments, thewater storage receptacle 102 comprises food grade plastic so as to provide a sanitary storage container for drinkable water, such as the drinkable water produced in accordance with various embodiments bywater purification system 100. - In accordance with embodiments, generally, a
filter 106 in portablewater purification system 100 can be any porous material through which water can be passed in order to remove at least some particulate matter from the water. A wide variety offilter 106 materials and methods are known in the art, including reverse osmosis filters 106. Functionally, areverse osmosis filter 106 receives an input of water containing a certain starting concentration of contaminants or impurities and produces two outputs: purified water with a contaminant concentration much lower than the starting concentration and brine water with a contaminant concentration higher than the starting concentration. A reverse osmosis filter achieves this result by the use of a pressure differential across a selective membrane. The selective membrane has pores sized to be smaller than a contaminant particle size but large enough to allow the passage of water molecules. Thus, as contaminant-bearing water is placed under sufficient pressure on a first side of the selective membrane, water molecules pass through the membrane to the second side, while the contaminant particles too large to pass through the membrane pores are retained on the first side. The water accumulated on the second side provides the purified water output, while the water on the first side—with the retained contaminants—provides the brine output having a higher concentration of contaminants (i.e., the concentration increases on the first side of the selective filter because the amount of water there decreases—due to water siphoning off through the selective filter—but the total amount of contaminants remains the same). In many instances, salt is the targeted contaminant, and areverse osmosis filter 106 can receive an input of seawater or other saltwater and produce a freshwater or at least drinkable (i.e., potable) output and an output of brine having a salt concentration slightly higher than the input saltwater. - In embodiments, for operation of the
purification system 100, asource water intake 108 can be connected to a source of water to be purified (e.g. salt water or water containing an undesirable level of contaminants), such as by a hose, pipe, tube, spigot, spout, or other appropriate conduit. Thepump 104 can be utilized to provide the pressure and/or flow necessary to move the source water provided by anintake 108 through thefilter 106 to accomplish purification. The purified water outputted by thefilter 106 can be routed into thewater storage receptacle 102 for later use. In embodiments, the brine outputted by areverse osmosis filter 106 can be disposed of in any acceptable manner. For example, when thepurification system 100 is used with seawater, the brine can be routed back to the sea where it is quickly diluted. - In embodiments, the
water storage receptacle 102 can have alid 110. Sealing thewater storage receptacle 102 can advantageously limit the risk of introducing contaminants into the purified water contained within thewater storage receptacle 102. Thelid 110 can have agasket 112 to ensure thatwater storage receptacle 102 is well sealed when thelid 110 is in place. In embodiments,lid 110 has one ormore latches 114 to ensure thatwater storage receptacle 102 is well sealed when thelid 110 is in place. Thelid 110 can also have one ormore handles 116 to facilitate opening, closing or positioning of thelid 110 on thewater storage receptacle 102. - In various embodiments, additional or supplemental measures can be utilized to minimize the risk of purified water becoming contaminated during storage. For example, in embodiments, the interior of the
water storage receptacle 102 can be treated with a disinfectant prior to introducing purified water therein. In some embodiments, clear sterile plastic bags or liners can be utilized inside thewater storage receptacle 102 to ensure that purified water introduced into thewater storage receptacle 102 is not exposed to any contaminants that have been introduced into thereceptacle 102. - In some embodiments, the
water storage receptacle 102 has an airpressure release valve 118 configurable to release air pressure buildup within thewater storage receptacle 102. In embodiments thewater storage receptacle 102 has a hose, pipe, tube, spigot, spout, or other appropriate conduit to serve as apurified water output 120 for draining thewater storage receptacle 102 and/or for transferring purified water to other containers. - In embodiments, the
water storage receptacle 102 is outfitted withwheels 122.Wheels 122 can provide thewater purification system 100 with improved ease of portability when thepurification system 100 is not operating. Although only one of twowheels 122 is shown inFIG. 1 , any number ofwheels 122 can be used in varied embodiments, including just onewheel 122, threewheels 122, fourwheels 122, or more. In embodiments, thewater storage receptacle 102 is outfitted with tie-downs 124 or the like. Tie-downs 124 can be used to stabilize thewater storage receptacle 102 when thepurification system 100 is operating. Although only one of fourtie downs 124 is shown inFIG. 1 , any number oftie downs 124 can be used in varied embodiments, including just one tie down 124, twotie downs 124, threetie downs 124, or more. -
FIG. 2 shows a bi-fold lockingsolar panels array 130 for use in the portablewater purification system 100 in accordance with embodiments. In embodiments, any suitable power source can be utilized to provide power for thepump 104. In various embodiments, thewater purification system 100 utilizes one or moresolar panels array 130 having one or moresolar panels 128 as a power source to provide power to thepump 104. As shown inFIG. 2 , in various embodiments, sevensolar panels 128 are arranged in asolar panels array 130 in a bi-fold locking pattern; however asolar panels array 130 can have any number ofsolar panels 128, which can also be arranged in a variety of other ways.Solar panels 128 can include a plurality of photo-voltaic cells as known in the art for converting light into electrical energy. - In various embodiments, a
solar panels array 130 can havevarious connectors 132 which interface withconnectors 126 on thewater storage receptacle 102 in order to support thesolar panels array 130 relative to thewater storage receptacle 102. In various embodiments, thesolar panels array 130 can havetie downs 134 in order to secure thesolar panels array 130 in place during operation of thepurification system 100. Asolar panels array 130 in embodiments can be adjusted and secured so as to refine the array's 130 orientation relative to the sun, and in various embodiments, the variability provided by the combination oftie downs 134 andconnectors 132 provide thesolar panels array 130 with this adjustability. Accordingly, in many embodiments, thesolar panels array 130 can be aligned differently according to the season and time of year so as to maximize the solar panels array's 130 collection of solar energy. -
FIG. 3 shows a left rear view of a portablewater purification system 100 in accordance with embodiments. As shown inFIG. 3 , in various embodiments,purification system 100 can also comprise one ormore batteries 136. In embodiments, abattery 136 can be used as a power source for thepump 104. Abattery 136 can provide a stable source of electric energy, which can also be an advantageous addition to a system usingsolar panels 128.Solar panels 128 may often produce a constantly varying level of energy based on constantly varying intensity of sunlight, and electrical energy production from asolar panel 128 may suddenly drop or cease all together during cloudy or night-time periods or in other scenarios in which direct light is otherwise inhibited or obscured. In various embodiments, one or moresolar panels arrays 130 are used to charge abattery 136, which in turn is used topower pump 104. Apower inverter 138 can also be used in accordance with various embodiments to convert electrical energy between direct current (DC) and alternating current (AC) as necessary to provide thepump 104 with the appropriate form of electrical energy. In some embodiments, avoltage transformer 140 is also provided to adjust the voltage level provided by thebattery 136 and/orsolar panels 128 to the level necessitated by the model and type ofpump 104 used inpurification system 100. - As shown in
FIG. 3 , in some embodiments, abattery tray 142 can be provided to support thebattery 136, theinverter 138, and/or thetransformer 140 relative to thewater storage receptacle 102. In some embodiments, thebattery tray 142 can be hingedly connected to thewater storage receptacle 102 or otherwise configured to be stored to make thepurification system 100 more compact to facilitate the movement or relocation of thepurification system 100. In various embodiments, one ormore handles 144 are also provided onwater storage receptacle 102. In embodiments, handle 144 placement can further facilitate the ease of movement or relocation of thepurification system 100 by a user. - As shown in
FIG. 1 , in some embodiments one or both of thepump 104 and thereverse osmosis filter 106 are located in integrated housing within thewater storage receptacle 102 during operation and/or transport of thewater purification system 100. However, in various embodiments, this is not the case, and either one or both of thepump 104 and thereverse osmosis filter 106 can be located outside of thewater receptacle 102 during operation or transport of thesystem 100. For example,FIG. 4 shows a portable water purification configured for operation in accordance with embodiments. As may be seen inFIG. 4 , in embodiments, thepump 104 can be located outside thecontainer 102 and deliver source water to thefilter 106. In embodiments, thefilter 106 can be located outside thecontainer 102 and provide purified water to be stored in thecontainer 102. In embodiments,solar panels arrays 130 can be set up outside of thecontainer 102 and operable to provide power to thepump 104. In some embodiments, thesolar panels arrays 130 can be connected to the outside of thecontainer 102, such as byconnectors 126. In other embodiments, thesolar panels arrays 130 can be utilized without being mounted on thecontainer 102. -
FIG. 5 shows a portablewater purification system 102 utilizing apower source 152 in accordance with embodiments. In addition topower sources 152 discussed in more detail in the disclosure herein, in embodiments, thepump 104 can be powered by one or moreother power sources 152 known in the art including, but not limited to, a combustion engine; a steam engine; a Stirling engine powered by either direct sunlight or sunlight amplified through a lens such as a Fresnel lens; a Stirling engine powered by heat from burning wood, coal, or other fuel; a turbine harnessing wind, water, or geothermal energy; and/or mechanisms such as cranks that are operable to allow manual operation of the pump by hand for an individual or through harnessed work of livestock. -
FIG. 6 shows apositioning apparatus 200 configured with aStirling engine 202 in accordance with embodiments. In embodiments, apositioning apparatus 200 can include an enclosure 204 with a Stirling engine 204 located therein. In embodiments, alens 206 is located at or near the top of the enclosure 204. Thelens 206 may be any suitable type of lens and may be constructed of any suitable material. However, in various embodiments, thelens 206 is a Fresnel lens, and in embodiments, the lens is constructed of a polycarbonate material. In various embodiments, thelens 206 is positioned so as to focus solar energy on the Stirling engine 204. In embodiments, the solar energy is focused on a heat exchanger of the Stirling engine 204, providing the heat differential necessary to cause engine parts to move and generate electricity. The enclosure can further include apower output connection 208 in various embodiments by which an electrical device, for instance, apump 104 or abattery 136, can access the electricity generated by theStirling engine 202. In embodiments, the enclosure 204 can also include an ambient heat vent 210 to release heat build up within the enclosure 204. - In various embodiments, the
positioning apparatus 200 can be adjusted in order to modify the orientation of thepositioning apparatus 200 and/or of thelens 206 relative to the sun. This modified positioning can advantageously allow for increased collection of solar energy, thereby improving the performance of theStirling engine 202. In various embodiments, thepositioning apparatus 200 can include one or more adjustable legs 210 connected to a base of thepositioning apparatus 200. The one or more adjustable legs 210 can be adjusted individually or collectively in order to reorient the positioning of theapparatus 200 and/or thelens 206. In embodiments, thepositioning apparatus 200 can also have one or more fixed supports—such as thecurved support 212 shown in FIG. 6—to provide additional stability during and/or after positioning by the one or more adjustable legs 210. Additionally, whileFIG. 6 (as discussed below) shows apositioning apparatus 200 having two legs 210 and onesupport 212, any number of legs and any number of supports may be used. The legs and support members can support the base of the positioning apparatus relative to a support surface. Each leg and each support member can contact the support surface at a location distinct from where any other leg or support contacts the support surface. Each leg and each support member can contact the base at a location distinct from where any other leg or support contacts the base. - In an example embodiment shown in
FIG. 6 , thepositioning apparatus 200 has a first adjustable leg 210 a at a rear left corner, a second adjustable leg 210 b at a rear right corner, and acurved support 212 extending down from a front face. In this embodiment, pitch (represented as an angle α inFIG. 6 ), can be modified by adjusting the legs 210 a and 210 b by the same amount in the same direction so that thepositioning apparatus 200 tilts in a forward or backward direction. In this embodiment, roll (represented as an angle (3 inFIG. 6 ), can be modified by adjusting the legs 210 a and 210 b by the same amount in opposite directions so that thepositioning apparatus 200 tilts in a left or right direction. Additionally, in this embodiment, the legs 210 a and 210 b can be adjusted by differing amounts in order to modify both pitch and roll at the same time. The curvature of thecurved support 212 in this embodiment allows the front of thepositioning apparatus 200 to always have a third point of contact with the surface supporting thepositioning apparatus 200, regardless of the pitch and/or roll provided by the legs 210. Accordingly, as shown inFIG. 6 , in various embodiments, thepositioning apparatus 200 and/or lens can be adjusted relative to the sun (e.g., oriented perpendicular to the sun) to adjust and/or maximize collection of solar energy. - According to differing embodiments, these positioning adjustments may be performed manually and/or automatically. In some embodiments, a
light direction detector 214 is provided to facilitate automatic positioning of thepositioning apparatus 200. In embodiments, the light direction detector includes anenclosure 216, anaperture 218, andlight sensing surface 220. In operation in various embodiments, theaperture 218 allows a small amount of sunlight to pass through the exterior of theenclosure 216 and reachlight sensing surface 220. In embodiments, theaperture 218 limits the sunlight passing through it such that the sunlight only illuminates a small portion of thelight sensing surface 220. Because the angle at which sunlight passes through theaperture 218 correlates to the sun's location in the sky, the sun's orientation is accordingly also indicated by the portion of thelight sensing surface 220 that is illuminated by the sunlight passing through theaperture 218. In embodiments, thelight sensor surface 220 is configured to detect which portion of thelight sensor surface 220 is illuminated, and this detection can be used to adjust the orientation ofpositioning apparatus 200 orlens 206. For example, in some embodiments, thelight sensor surface 220 is operably configured to control one or more servos that adjust the height of one or more legs 210, thereby altering the pitch and/or roll of thepositioning apparatus 200 orlens 206 and affecting the amount of solar energy collection. In varying embodiments, thelight sensor 220 can be operable for servo control by electronic circuitry, by use of a processor, or by any other appropriate means known or later developed in the art. - Additionally, while descriptions of a
positioning apparatus 200 have thus far been primarily directed to configuration with a Stirling engine, thepositioning apparatus 200 is not so limited. Thepositioning apparatus 200 could also be configured with other components disclosed herein, including, but not limited to, configuration with asolar panels array 130. Furthermore, thepositioning apparatus 200 can be used independently of water purification systems and may be utilized in any setting to adjust the orientation of an object relative to the position of the sun in the sky. - In embodiments, the
water purification system 100 can have one or more monitors 146. In some embodiments, amonitor 146 is integral with thewater storage receptacle 102 or thelid 110, and in some embodiments amonitor 146 is inset so as to be flush with the surface of thereceptacle 102 orlid 110. However, in embodiments, amonitor 146 is not integral with thelid 110 or thereceptacle 102 and can be moved or relocated as a separate component. - In some embodiments, a
monitor 146 can be operatively coupled with thewater storage receptacle 102 so as to provide a display reflecting water and/or flow characteristics. For example, thewater purification system 100 can have one or more sensors operatively coupled with the water storage receptacle and operable to provide data corresponding to at least one of flow characteristics or water characteristics. Amonitor 146 may be configured to display data provided by the one or more sensors. In some embodiments, amonitor 146 can be operatively coupled with thepower source 152 so as to determine and/or provide a display reflecting power generation and/or consumption levels. In some embodiments, amonitor 146 can display an estimate of rates, times, and/or quantities regarding how much water can be purified based at least in part on the determined amount of power, water, and/or flow characteristics. In accordance with a variety of different embodiments, amonitor 146 can be configured to show one or more characteristics including, but not limited to, intake flow, output flow, pH levels, organic parts per million (ppm), mineral ppm, power generated, power consumed, and battery charge level. - In some embodiments, a
monitor 146 can also act as a regulator. For example, in some embodiments, amonitor 146 can be used to adjust power consumption and/or storage aspects. In some embodiments, amonitor 146 can be configured to inject pH balance equalizer. In some embodiments, amonitor 146 can be used to display and/or set a water quality setting. For example, water quality can range on a descending scale according to whether the water would be acceptable for medical treatment, drinking, cooking, hand-washing, bathing, or irrigating, but water quality setting levels also need not be so limited. In an example embodiment, the water quality setting could be adjusted to allow a higher ppm in the output water, based at least in part upon different factors such as a reduced level of required purification (e.g. to produce water for irrigating rather than drinking) or power considerations (e.g. to conserve power during shortages). - In embodiments,
water purification system 100 has a float cut-off switch 148. A float cut-off switch 148 can be configured to deactivate thepump 104. In embodiments, a float cut-off switch 148 is configured to deactivate thepump 104 based on the water level in thewater storage receptacle 102. In embodiments, the float cut-off switch 148 can be calibrated to automatically deactivate thepump 104 when the water level reaches a designated level. - In some embodiments, one or more component mounts 150 are provided.

component mount 150 can be configured to support one or more of a number of different components of thepurification system 100 relative to thewater storage receptacle 102. For example, as depicted inFIG. 5 , in accordance with a variety of different embodiments, acomponent mount 150 can be configured to support one or more components including, but not limited to, apump 104, afilter 106, a power source 152 (e.g. a Stirling engine, asolar panel 128, abattery 136, or another way to supply power to apump 104 or a monitor 146), a Fresnel lens, asolar panels array 130, abattery 136, apower inverter 138, atransformer 140, alid 110, a tie down 124, or amonitor 146. - In various embodiments, the
water storage receptacle 102 can be used to primarily store water in one configuration and to primarily store components in another configuration. In embodiments, the contents of thewater storage receptacle 102 depends upon whether thewater purification system 100 is in a transport or an operate mode. In an example embodiment, during initial fabrication of thewater purification system 100, individual components including apump 104, areverse osmosis filter 106, a bi-foldsolar panel array 130, and abattery 136 are packed into awater storage receptacle 102 to be in transport mode for relocation of thesystem 100 to a site where water is to be purified. Upon arrival to the site, a user can remove these components from thewater storage receptacle 102 and convert thesystem 100 into an operation mode by plugging a power output cord from thearray 130 into thebattery 136 for charging, connecting the battery to thepump 104, and coupling thepump 104 and thereverse osmosis filter 106 between a water source and thewater storage receptacle 102 so that a purified water output is routed intowater storage receptacle 102. Thus, in this example embodiment, during operation of thesystem 100, components are no longer stored in thewater storage receptacle 102, but purified water is stored therein. When thesystem 100 needs to be moved in this example embodiment, a user can convert thesystem 100 back from operation mode to transport mode by draining most or all of the water from thewater storage receptacle 102 and placing most or all of the components therein so that thewater storage receptacle 102 is primarily storing components and can be more easily moved as a unit. In further example embodiments, more or fewer components can be included in thewater purification system 100 and/or components are connected in different orders and/or arrangements. - In some embodiments, the
water purification system 100 is sized for storage or transport in great numbers. For example, as shown inFIG. 1 , in embodiments, thelid 110 and the bottom of thewater storage receptacle 102 can be flat so that onewater purification system 100 can be stacked upon anotherwater purification system 100 for storage or transport. In some embodiments, the bottom of awater storage receptacle 102 has a recess shaped to accommodate amonitor 146 or other feature protruding from the top of anotherwater purification system 100 when thesystems 100 are stacked. Additionally, in some embodiments, thewater purification system 100 is sized to accommodate transport in uniform shipping containers as known in the art. One such embodiment is shownFIG. 3 , where thewater purification system 100 has a height dimension of 54 inches and a square lid dimensioned at approximately 24 inches per side; a set of such water purification systems could be stacked two high and four wide in most standard shipping containers. -
FIG. 7 is a simplified block diagram illustrating steps of amethod 400 for purifying water, in accordance with an embodiment. In embodiments, thewater purification system 100 can be used in practicing themethod 400. Instep 402, at least one of a pump, a reverse osmosis filter, and/or a power supply is removed from a container. Instep 404, at least one of the pump, the reverse osmosis filter, and/or the power supply removed instep 402 are assembled in a configuration with the container fromstep 402 to remove at least an impurity from source water. Instep 406, at least one of the pump, the reverse osmosis filter, and/or the power supply assembled instep 404 are operated to remove at least the impurity from the source water to produce potable water. Instep 408, the potable water produced instep 406 is stored in the container from which the items were removed instep 402. - Other variations are within the spirit of the present invention.
